Isagi's team cinched a win due to the awakening of Barou as a villain on the field. To cause more chemical reactions in the fourth stage, they picked one player from the other team, who demonstrated ego to devour them during the game. In the meantime, Bachira and the Top 3 are looking for the next opponent. Rin sees through Bachira's "monster" during their training, which forces Bachira to face his own ego.
Yup. That "monster" must be 
a friend only you can see.

لا يمكن أن يراه سِواك
Ja. Dieses „Monster“

un amigo que solo ves tú.
Sí. Ese monstruo debe de ser
un amigo que solo ves tú.

Isso. Aquele "monstro" deve ser um 
amigo que só você consegue ver.
Да. Скорее всего, это твоё чудовище —
друг, которого видишь только ты.
